Stay a student of life.
At some point many of us stop learning. We've got our degree, our job, our opinions. We know how things are.
But life keeps teaching, if we let it. Every person we meet knows something we don't. Every season has something new to show us.
The wisest people I know are still students. Curious, open, a little amazed.
Keep your school bag packed. The best lessons may still be ahead.
